Protective Frame Wrapping Display Module for Narrow Mobile Phone Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone designs face challenges in maximizing the visible screen area without increasing the phone's size, as the frame width is often enlarged due to the use of a housing step for connecting the screen and housing, which can lead to glue spills and faults in the display module.
Innovation Solution
A component design where the screen includes a protective frame that wraps the display module, with glue applied to the side face of the screen, allowing direct connection to the housing, forming multiple joint faces for secure, waterproof, and dustproof bonding, thereby reducing the frame width and enhancing connection stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a housing step is used to connect the screen and housing with glue, then connection stability is improved, but the frame width increases and screen visible area ratio decreases
Solution Approach 1:
The patent transitions from connecting the screen to the housing at a horizontal position (housing step) to connecting at a vertical position (side face of the screen). This dimensional change allows the glue to be applied directly to the side face of the screen, eliminating the need for a housing step and reducing the frame width while maintaining connection stability.
2Reliability
If a housing step is used for glue dispensing, then connection stability is improved, but glue may spill and cause faults or appearance flaws
Solution Approach 1:
The patent extracts and eliminates the housing step from the structure, allowing glue to be applied directly to the side face of the screen. This removes the problematic interface where glue could spill into the gap between the display module and housing, preventing both functional faults and appearance flaws while maintaining secure connection.
3Length of moving object
If the frame width is reduced to maximize screen visible area, then screen visible area ratio is improved, but connection stability between screen and housing deteriorates
Solution Approach 1:
The patent connects the screen to the housing at a different spatial location (side face instead of top edge), enabling frame width reduction while preserving connection stability through direct bonding at the new interface.
Solution Approach 2:
The side face of the screen is prepared with a flat surface in advance, providing an optimal bonding interface for glue application. This preliminary preparation ensures stable connection even with reduced frame width by creating a dedicated bonding area that compensates for the reduced overall connection area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design maximizes the visible screen area without increasing the phone's size, providing better connection stability and protection against environmental factors like water and dust.
Implementation Method 1
the screen is fastened by adhering the CG to the housing... The glue is flattened and spills and extends towards both sides, forming adhesion between the CG and the housing

AI summary
Embodiments of the present invention disclose a component including a housing and a screen. The screen includes cover glass, a touch panel, and a display module, and the display module, the touch panel, and the cover glass are connected in sequence from the bottom to top. The screen further includes a protective frame, and the protective frame wraps the bottom and a side face of the display module. Glue is disposed on a side face of the screen, and the housing is connected to the screen by using the glue. The present invention provides a component including a housing and a screen, and a protective frame is disposed on a display module of the screen. A backlight plate of the display module is wrapped by the protective frame. The embodiments of the present invention resolve a problem of an excessively large width of a frame of a mobile phone, so that the display module and the cover glass are directly connected to a side face of the housing. In this case, a width of a frame of a mobile phone can be reduced, and therefore a ratio of a visible area of the mobile phone screen is maximized, and a size of the mobile phone is also controlled. Therefore, a user can experience a larger visible area without increasing the size of the mobile phone.
